I have one of those, it holds really well. It helps to moisten the suction cups a little, I spray the, with a bit of window cleaner before I stick them to the window. What I’d like to know is where I could get another iPad holder like the on3 I got with my FieldView kit several years ago. Seems like all of them are spring loaded sideways. It’s hard to press the Home button on the iPad with those. The one that came with the FieldView kit has a piece on top of the iPad that is spring loaded
